[piquark6046]

Make parkedDomain2 visit a domain directly via got npm package to confirm that the domain is parked or not by following the steps:

1. Make a HTTP request to a provided domain. (HTTPS-first mode OR HTTPS-only mode)
2. Make a decision by the following conditions:
   • If the web server has no responses ¹ or returns HTTP 4XX error code, parkedDomain2 will consider the domain as alive.
   • If the web server returns a normal webpage as HTML, javascript, CSS, etc, parkedDomain2 will make decision as what the domain is alive.
   • If none of the above conditions are met, continue the steps.
3. If it detects what status of the domain is 'sell' or 'parked' by processing the received HTML string, the domain will be consider as parked (following redirection is also included)
